COMPOUND GEARING FOR AIR-PUMPS.

SPECIFICATION forming part of Letters iatent No. 339,654, dated April 13, 1886.

(No model.)

To all whom it 77mg concern:

Be it known that I, LOUIS 0. HUBER, a citizen oi' the United States, residing at Huber, in the county of Bullitt and State of Kentucky,

haveinvented certain new and useful Improvements in Compound Gearing for Air-Pumps; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to lo which it appertains to make and use the same,

reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

l 5 Figure l of the drawings is a representation of a front elevation, partly in section. Fig. 2

This invention relates to improvement in mechanism for driving rotating cylinder air-pumps to produce constant air-pressure; and it consists in the arrangement of gearing and lifting-weights and the combination of the same with the driving-shaft of the ma chine, the same arrangement and combina' tion being hereinafter described, and pointed out in the appended claims.

Referring to the accompanying drawings by letter, A designates the outer stationary cylinder of the pump, supported by any proper means.

A is the cylinder-head, and B the shaftof the internallyrotating cylinder, passing through the center of the head A.

C is a plate bolted centrally to the outside of the head A, and having the shaft B passing through it, and O is a rectangular frame of proper size bolted to the plate and standing at right angles outward from the same. D D are similar upright brackets bolted by their lower ends to the side bars of the frame 0, one at the outer end of the same and the other a sufficient distance inward from the former.

E is a shaft turning in bearings made centrally in the transverse top bars, (I d, of the brackets, and carrying 011 its end extended inward beyond the inner bracket a large gearwheel, a. F F" are similar opposite shafts turning in bearings made in the ends of the top bars of the brackets and carrying on their respective inwardly-extended ends the small gear-wheel e, on opposite sides of the same, slightly below its central line.

H is a gear-wheel splined on the outer end of the shaft 13 and arranged to mesh with the 5 gear-wheel c. The wheel H has on its inner side a boss provided with a circumferential groove, with whichthe forked inner arm of alever, 71-, engages. The said lever is pivoted upon one of the side beams of the frame 0, 6c and by moving its outer arm the gear-wheel H can be thrown into and out of engagement with the gearwheel c. I I are similar drums secured,respectively, on the shafts F F between the brackets D, and turning therewith, 6 5 and i t" are wire ropes secured in the said drums, wound in the same direction around the latter, and passing thence upward from corresponding sides of the drums to pass over the pulleys K K, secured in proper supports. The ropes have secured to their depending ends the similar weights, is k, which tend to rotate the drums. The rope 11 passes over but one pulley, but the rope 'i, as it rises from the inner side of the drum 1, passes over two, to 7 5 give the weight clearance room. The outer end of the shaft F extends beyond the front bracket and is squared, for the connection of a crank-handle, L, by means of which the wire ropes are wound up on the drums and the weights elevated.

\Vhen it is desired to operate the pump, the gear-wheel H is thrown out of engagement with the gear-wheel e by the lever h, the crank-handle connected with the shaft F, and the weights elevated. The gear-wheel H is then again thrown out of engagement and the crank-handle removed, when the descent of the weights, by means of the ropes, drums,and intermeshing gearing will rotate the shaft B, 0 and consequently the internal cylinder. As

the said cylinder has to rotate through and against water, and there is considerable friction between the interineshing gearing, the weights will descend at a very slow rate, it 5 being found in practice that it takes from twenty-five to thirty days for theruto descend about thirty feet, whereas no other device for the same purpose has been made to operate longer than eight days. The actuating of the shaft 13 by equal weights on the opposite sides is a further advantage, as it equalizes and steadies the motion thereof.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. The combination, with the actuatingshaft of a rotary cylinder air-pump and a gear-wheel on said shaft, of the gear-wheels e f g, sceured,respeetively, on the shafts E F F, turning in bearings in a frame adapted to be bolted to the head of the stationary cylinder of the pump, the gear-wheel 6 being arranged to mesh with the gear-wheel on the shaft, the drums I I, secured to shafts F F, respectively, the wire ropes 2' '6, respectively secured to the drums I I, and the weights k, attached to the depending arms of said ropes, substantially as specified.

2. The combination, with the stationary cylinder-head A, the shaft B of the rotating cylinder, the gear-wheel H, splined on said shaft, and the actuating-lever h, of the plate 0, frame 0, shafts E F F, gear-wheels eff, drums II, wire ropes t i, pulley K, Weights k, and crankhandle L, all constructed and arranged substantially as shown and described, for the purpose specified.

In testimony whereof I affix mysignature in presence of two witnesses.

LOUIS O. HUBER.
